UMSA - Ultimate SCART Adapter

Support Thread for Soft15Khz


Q: I don't know what this 15Khz thing means. Never heard about Soft15Khz and I don't care. Should I buy this device and expect it just works?
A: Using UMSA means that a 15 Khz input signal is needed. Make sure your device is prepared to output 15Khz.

Q: There is a MOLEX Floppy Powercable footprint on the UMSA PCB. Can I use this one to power up UMSA instead of using the power plug?
A : Sure, this avoids having several PSUs in your cab.

Q: I`ve connected the VGA cable and the scart cable. But sound is missing?
A: The VGA cable doesn't carry sound. Plug the sound interface to the cinch plugs.

Q: So I`ve plugged a 31Khz VGA graphic card to the UMSA. I don't see a picture. Why?
A : UMSA only accepts 15Khz. Use Soft15Khz.

Q: Do I need a power supply unit?
A: Yes.
